Gantt throwing TypeError

Added by William Wedin over 15 years ago

Hi all. I just got Redmine going on my server this morning, and I'm having some trouble with Gantt. If a project has a ticket and that ticket has a due date, browsing to the Gantt page for that project produces an error. Does anyone have some insight that could point me in the direction of a fix? Thanks!

Here are the details:

TypeError in Issues#gantt

Showing issues/gantt.rhtml where line #192 raised:

can't convert Date into Float

Extracted source (around line #192):

189:
190: i_late_date = [i_end_date, Date.today].min if i_start_date < Date.today
191:
192: i_left = ((i_start_date - @gantt.date_from)*zoom).floor
193: i_width = ((i_end_date - i_start_date + 1)*zoom).floor - 2 # total width of the issue (- 2 for left and right borders)
194: d_width = ((i_done_date - i_start_date)*zoom).floor - 2 # done width
195: l_width = i_late_date ? ((i_late_date - i_start_date+1)*zoom).floor - 2 : 0 # delay width

I did find a solution for this, after debugging it. i_end_date was something like a datetime, which apparently can't be compared with a date. I'm no Ruby expert, but this seems strange to me, double so because no one else seems to have this problem. Nevertheless, it was fixed with the following three lines of code at line 189:

i_start_date = i_start_date.to_date();
i_end_date = i_end_date.to_date();
i_done_date = i_done_date.to_date();

Is this perhaps an artifact of running on Windows?

Linux has the same problem (RH el5, RM 0.8.4, Database: Oracle, Rails 2.1.2)

Fixed by your code.
